(AP) - The Republican primary race for governor of South Dakota is well on its way to being the costliest in state history with Attorney General Marty Jackley and Congresswoman Kristi Noem already having about $3.8-million dollars combined.

Year-end campaign finance reports shows Jackley outraised Noem last year...$1-million to $900,000 in cash and donated goods and services...but Noem ended the year with more money...$2.1-million to $1.6-million

Both outstripped the only Democrat in the race, State Senate Minority leader Billie Sutton, who raised more than $870,000 and closed out 2017 with about $664,000 on hand. If he remains without a challenger, Sutton would be poised to conserve cash while Noem and Jackley campaign for the June primary election.
